IOIO Board for Android Control

IOIO Board for Android Control

Microcontroller can control device.Now Android Mobilephone can control also with IOIO Board.

The IOIO (yo-yo") is a board specially designed to work with your Android device (OS versions 1.5 and greater). The board provides robust connectivity to an Android device via a USB connection and is fully controllable from within an Android application using a simple and intuitive Java API -no embedded programming or external programmer will ever be needed!

So far, the devices proven to work are: G1, Nexus One, Nexus S, Motorola Droid X. If you get the IOIO working on your Android device, please let us know in the comments below, thanks!

The IOIO board contains a single MCU that acts as a USB host and interprets commands from an Android app. In addition, the IOIO can interact with peripheral devices in the same way as most MCUs. Digital Input/Output, PWM, Analog Input, I2C, SPI, and UART control can all be used with the IOIO. Code to control these interfaces is written in the same way as you write an Android app with the help of a simple to use app-level library. In other words, you can combine the awesome computing power, Internet/Bluetooth connectivity, touch screen, and a variety of sensors from your Android device with the ability to easily add peripheral devices to interact with the outside world. Also, using the IOIO does not require any hardware or software modifications to your Android device, thus preserving the warranty as well as making the functionality available to non-hackers.

If you are new to the IOIO or developing apps with Android, please use these resources to help get started:

Introduction

This is the beginners guide for the IOIO for Android board and is
intended for users that have never written an Android app. The goal of
this tutorial is to show how to write a simple app that communicates
with the IOIO board.

The programming language used to write an Android app is Java. If you
are not familiar with Java, this tutorial will only go over writing a
simple Java app using the IOIO library. This tutorial will not
cover how to write Java code nor will it cover how to use the rich
features within your Android device, like GPS, accelerometer, touch
screen, etc. Once you get to the point where you want to use the vast
array of features on your Android, we suggest first looking at the technical resource
section on developer.android.com. If you still can't find the examples
you are looking for, simply browsing the web will result in a ton of
information and examples that show you how to communicate with all of
the great pieces of hardware within your Andriod device.
In general, the holy grail for developing Android apps is developer.android.com.
There, you will find most of the information on Android development.
For documentation/downloads specific to the IOIO and for more advanced
discussions about the IOIO, see these links:

Gathering Your Hardware

5-15V power supply with at least 1A of current. You will need to power
the IOIO through the VIN and GND pins or there is an optional JST connector on the back of the board. It will need to be soldered into place and can be used with this adapter and wall wart power supply. More information at the end of the tutorial found here.

Installing the Development Environment

The Eclipse IDE (integrated development environment), the Android SDK
(software development kit), and the JDK (Java development kit) are the
primary pieces of software that you will need to install. The
page developer.android.com has written thorough instructions on what
exactly you will need to download. Please read the instructions
carefully, they are found in the link below:

ATTENTION: You must use JDK v6 (not v5 or v7) for Android development.
If you have any problems, see the Troubleshooting section from developer.android.com.
When you reach Step 4 in the Android SDK tutorial, you will at least
need to install the SDK components relevant to the Android device you
will be working with. For example, if you have an Android phone, goto Settings > About Phone and scroll down to Android Version. You must install the SDK platform corresponding to the Android version of your device.
